[Wikimedia-l] Copyright infringement - The real elephant in the room

[Andrew Gray]

It could use abuse-filter tags, just not in an entirely standard way:

* Bot scans edit X
* Script flags it as a problem
* Bot makes edit X+1 to page (perhaps adding copyvio template?) which
triggers an abusefilter rule for (if this bot and does such-and-such
an edit) and tags it.

The offending edit itself won't be tagged, but the page history will
and it can probably be spotted quite easily from there.
